For the start of my upcoming Deadlands campaign I created a plan and battlemap for an assumed Iron Dragon station in Chicago (start of their line to Seattle). It's inspired by the 1881 Union Depot, the pre-cursor of Chicago's big Union Station.

Most useful is perhaps this A1 battlemap of the entrance hall. It could be used for a variety of scenarios.
